A method, medium, and apparatus encoding and/or decoding an image in order to increase encoding and decoding efficiency by performing binary-arithmetic coding/decoding on a binary value of a syntax element using a probability model having the same syntax element probability value for respective context index information of each of at least two image components.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of decoding a predicted image of a current image, the method comprising: obtaining a predicted direction of luma component of the current image; obtaining a predicted direction of chroma components corresponding to the predicted direction of luma component in one of predetermined decoding modes; and decoding the predicted image of the current image based on the predicted direction of the luma and chroma components, wherein the predicted direction of chroma components is identical to the predicted direction of the luma component.
2. A non-transitory computer readable medium comprising computer readable code to control at least one processing device to implement a method of decoding a predicted image of a current image, the method comprising: obtaining a predicted direction of luma component of the current image; obtaining a predicted direction of chroma components corresponding to the predicted direction of luma component in one of predetermined decoding modes; and decoding the predicted image of the current image based on the predicted direction of the luma and chroma components, wherein the predicted direction of chroma components is identical to the predicted direction of the luma component.
